Determining milling parameters of a pear shaped ball mill

Determining milling parameters of a pear shaped ball mill

Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals.ball mill machine 30 50 per hour tons 2. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
